Strange error trying to run Query Task

Question

I have been attempting to query all features in a layer and just return one field. Is this allowed? I cannot get it to work with any of my map services, but examples I have looked at in the API reference documentation do not always specify where clauses or objectIds to query, so that leads me to think it's allowed. I am trying to run this snippet, but every time I run it, it goes to the errorResults function: var printQLyr = new QueryTask("https://www.xyz.org/xyz/rest/services/HBM/HBD/MapServer/3"); printQuery = new Query(); printQuery.outFields = ["Name"]; printQLyr.execute(printQuery, printQResults, errorResults); function printQResults(featureSet) { var resultFeatures = featureSet.features; console.log(resultFeatures[0]); } function errorResults(message) { console.log(message); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This is the error message I receive (entirely unhelpful): Error at Object.A.m.load (init.js:1028) at init.js:87 at c (init.js:103) at d (init.js:103) at b.Deferred.resolve.callback (init.js:105) at c (init.js:104) at d (init.js:103) at b.Deferred.resolve.callback (init.js:105) at init.js:92 at h (init.js:107)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Even when I run this in the ArcGIS JS sandbox, I receive this error. I receive this same error for any map service I try (I change the outField when I change the map service so I know that's not causing an error). Additionally, if I add either a line like printQuery.where = "StateID = 'VA'"‍;‍‍ or printQuery.objectIds = [1];‍‍ The query will run perfectly fine and return the records. I can run the query in the REST API as long as I specify something in the "where" box or the "objectIds" box. If I specify nothing but an outField it will not return anything but I do not get an error message either. How do I query all features in a dataset? Feature layer settings:

Molly,

A Query does need a where or a geometry or an objectId. If you want all the records then just use where = "1=1";
